NVIDIA GTX 750 Ti & MSI GTX 750 Gaming Review

NVIDIA GTX 750 Ti & MSI GTX 750 Gaming Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 4.0, with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1080 using 8xAA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a 20-minute cooldown, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.

When you look at the cooling results, it's important to remember that the GTX 750 Ti core has a 60 watt TDP while the GTX 750 comes in at 55 watts. The absolutely tiny heat sink used on the reference GTX 750 Ti keeps the temperatures at a modest 63 °C under load at stock speeds, and 56 °C when overclocked. When you add non-stock cooling, such as we have on the GTX 750 Gaming, the load temperatures are lower than some high ends cards' idle temperatures at 39 °C, running a massive overclock under load.
